  Qeen publishes no rate limits anywhere, and no rate-limit response header was returned on any
  observed request. This is an honest zero, not an unchecked field. The only throttling behaviour
  found anywhere in Qeen's published surface is client-side, inside the browser SDK, and it
  governs event emission rather than API access — it is recorded below because it is the real
  runtime signal an integrator will encounter, but it is not a server-enforced limit.
